Opis:
This study contributes to the value co-creation theory in the context of the new product development process. The aim of this study is a comparison of interactions that lead to creation of value on public social media. The considered interactions are at diff erent stages of the new product development process: an idea generation and product development (crowdsourcing) and post-launch (product off erings). The place where interactions take place is Facebook fan page of a Polish clothes manufacturer. The DART model of value co-creation is the framework of the comparison. The results show that interactions at the stage of ideation and product development phase attracted more attention from the social media users than post-launch ones. Interactions at the stage of idea generation phase encouraged social media users to communicate with other social media users. It was rare with post-launch activities in the form of product off ering. The study is qualitative, based on a case study of a Polish clothes manufacturer with the use of an indepth interview and netnography.

Opis:
Human cytomegalovirus (HCMV) infection remains the leading cause of serious contagious complications after allogeneic hematopoietic stem cell transplantation. These infections in HCMV-seropositive recipients can be due to reactivation or reinfection. Different HCMV strains were identified by determining the genotypes isolated from repeatedly tested patients. The UL55 sequences encoding viral glycoprotein B (gB) have been chosen as the target gene. The region, in which the gB precursor protein is cleaved into two fragments by a cellular endoprotease, is characterized by genetic variability, and based on that HCMV is classified into four major genotypes: gB1, gB2, gB3 and gB4. Multiplex real-time PCR assay enabled both, HCMV gB genotyping, as well as simultaneous quantitative assessment of the detected genotypes. This study was carried out in 30 transplant recipients, from whom 105 isolates of HCMV DNA were genotyped. In 40% of recipients, a mixed infection with two or three genotypes was detected. Genotype gB1 dominated in general, and characteristically for mixed infections, the genotype gB3 or gB4 was always present. Although there were no significant differences in the load for each genotype, in case of multiple infections, the number of copies of gB1 genotype was significantly higher when compared to a single gB1 infection. In patients with mixed genotypes, chronic HCMV infections and graft versus host disease were observed more often, as well as antiviral treatment was less effective. It was assumed that these adverse effects can be related to the presence of gB3 and gB4 genotypes.

Opis:
Epstein-Barr virus (EBV), a member of the family Herpesviridae, is widely spread in the human population and has the ability to establish lifelong latent infection. In immunocompetent individuals the virus reactivation is usually harmless and unnoticeable. In immunocompromised patients productive infection or type III latency may lead to EBV-associated post-transplant lymphoproliferative disorder (PTLD). The aim of our research was to investigate the utility of PCR-based methods in the diagnosis and monitoring of EBV infections in bone marrow transplant recipients. Thirty-eight peripheral blood leukocyte samples obtained from 16 patients were analysed, in which EBV DNA was confirmed by PCR. We used semi-quantitative PCR to estimate the viral load and reverse-transcription PCR (RT-PCR) to differentiate between latent and productive EBV infection. In 14 patients we confirmed productive viral infection. We observed a correlation between higher number of EBV genome copies and the presence of transcripts specific for type III latency as well as clinical symptoms.
